This is something that has been driving me crazy for a while. Whenever I adjust a mask path, the resolution of the preview window drops to 1/2 and displays the words "Adaptive Resolution (1/2)" appear in the top right corner of the preview window.

This make it really difficult to make precise adjustments. Is there a way to prevent resolution loss when adjusting mask paths? I've tried, to no avail, changing the Adaptive Resolution settings in the Preferences panel.
